I'm sure by now your neighbors all have their homes covered with spiderwebs and ghosts and pumpkins on the front porch...  and perhaps you have a few decorations out yourself.  I always find it tricky to not fall into the lure of the generic Target dollar-bin decorations.   I have nothing against them, and have a few myself, but it is also nice to have something original in your home.  
Here are a few ideas to get you out of your 'spook' style rut: 
My friend Meriel demonstrated this wreath on her blog.  I just LOVE how it turned out.  She chose a nude/orange tulle with black ribbon; also here it is in black tulle with orange ribbon (more spooky Halloweeny). 
Another idea is to create your own fall centerpiece.  My boys and I went on a fall walk in our neighborhood and gathered up some vibrant leaves, pine cones, and ferns.  Not bad for a completely FREE centerpiece, right?
I also love to change out the photos in my frames.  At Halloween time I'll put out past Halloween costume photos and pictures of pumpkins from the pumpkin patch.  It's a great trip down memory lane :)...sorry no pics because my computer is being weird...
 
For a more elaborate approach, here is an Edgar Allan Poe vignette to have in your entryway:
Happy decorating!
